我在录制webrtc会议时使用RecordRTC。实施录制后,当我测试此应用程序时,如果两个客户端都在同一系统上,那么它的工作正常。当我在不同的系统上测试此应用程序时,它不能正常工作,并且不会记录会议。
这是我停止录制客户端的代码。
recordRTC.stopRecording(function (videoURL) {
console.log('recordRTC.stopRecording Function inside');
SelectedFile = recordRTC.getBlob();
$('#uploadForm').append('#attachmentFileId', recordRTC.getBlob());
StartUpload();
});
var FReader;
var Name = "Meeting" + "_" + Date.now() + ".webm";
function StartUpload()
{
FReader = new FileReader();
FReader.onload = function (evnt)
{
socket.emit('Upload', { 'Name': Name, Data: evnt.target.result });
}
socket.emit('Start', { 'Name': Name, 'Size': SelectedFile.size });
}
socket.on('MoreData', function (data)
{
var Place = data['Place'] * 524288; //The Next Blocks Starting Position
var NewFile; //The Variable that will hold the new Block of Data
if (SelectedFile.webkitSlice)
NewFile = SelectedFile.webkitSlice(Place, Place + Math.min(524288, (SelectedFile.size - Place)));
else
NewFile = SelectedFile.slice(Place, Place + Math.min(524288, (SelectedFile.size - Place)));
FReader.readAsBinaryString(NewFile);
});
服务器端代码 我是从here得到的。
socket.on('Start', function (data) { //data contains the variables that we passed through in the html file
var Name = data['Name'];
Files[Name] = { //Create a new Entry in The Files Variable
FileSize : data['Size'],
Data : "",
Downloaded : 0
}
var Place = 0;
try{
var Stat = fs.statSync('Temp/' + Name);
if(Stat.isFile())
{
Files[Name]['Downloaded'] = Stat.size;
Place = Stat.size / 524288;
}
}
catch(er){} //It's a New File
fs.open("Temp/" + Name, 'a', 0755, function(err, fd){
if(err)
{
console.log(err);
}
else
{
Files[Name]['Handler'] = fd; //We store the file handler so we can write to it later
socket.emit('MoreData', { 'Place' : Place, Percent : 0 });
}
});
});
socket.on('Upload', function (data){
var Name = data['Name'];
Files[Name]['Downloaded'] += data['Data'].length;
Files[Name]['Data'] += data['Data'];
if(Files[Name]['Downloaded'] == Files[Name]['FileSize']) //If File is Fully Uploaded
{
fs.write(Files[Name]['Handler'], Files[Name]['Data'], null, 'Binary', function(err, Writen){
var input = fs.createReadStream("Temp/" + Name);
var output = fs.createWriteStream("Video/" + Name);
//util.pump(readableStream, writableStream, [callback])
//Deprecated: Use readableStream.pipe(writableStream)
input.pipe(output);
input.on("end", function() {
console.log("end");
fs.unlink("Temp/" + Name, function ()
{ //This Deletes The Temporary File
console.log("unlink this file:",Name );
//socket.emit('Done', {'Image' : 'Video/' + Name + '.jpg'});
});
});
});
}
else if(Files[Name]['Data'].length > 10485760){ //If the Data Buffer reaches 10MB
fs.write(Files[Name]['Handler'], Files[Name]['Data'], null, 'Binary', function(err, Writen){
Files[Name]['Data'] = ""; //Reset The Buffer
var Place = Files[Name]['Downloaded'] / 524288;
var Percent = (Files[Name]['Downloaded'] / Files[Name]['FileSize']) * 100;
socket.emit('MoreData', { 'Place' : Place, 'Percent' : Percent});
});
}
else
{
var Place = Files[Name]['Downloaded'] / 524288;
var Percent = (Files[Name]['Downloaded'] / Files[Name]['FileSize']) * 100;
socket.emit('MoreData', { 'Place' : Place, 'Percent' : Percent});
}
});
如果两个客户端在同一台机器/系统上工作正常,但如果两个客户端都在不同的系统上,则不会记录会议。
